Description

  The present invention relates to a louver configured with a plurality of blades and a fitting including the louver.

  Conventionally, there is a known louver that is configured to perform ventilation and lighting adjustment by arranging a plurality of slats in the vertical direction and rotating each slat in conjunction with the joinery installed in a building such as a house. There are also documents that disclose this (for example, see Patent Document 1).

  As disclosed in Patent Document 1, each blade of the louver is rotatably provided on the louver frame, and each blade is tilted so that the plate surface of each blade forms a steep slope. Due to this, the opening of the louver is closed.

Japanese Patent No. 4410373 Specification

  In recent years, there has been a growing demand for a more comfortable indoor environment through ventilation and temperature control, a reduction in air-conditioner power consumption through ventilation, and a reduction in lighting power consumption through lighting. Louvers have the potential to meet these demands. There are many requests for innovations and improvements in structure and function, improvement in safety performance, and realization of more diverse installation forms.

  In such a louver, for example, when considering application to indoor furniture such as a sliding door, there is a situation where it is necessary to block the passage of light in two spaces partitioned by the sliding door by completely closing the louver. is assumed.

  For example, when one room partitioned by a sliding door is a bedroom at night, the light of the other room is prevented from leaking into the bedroom, that is, it may be necessary to prevent light leakage.

  In this regard, as disclosed in Patent Document 1, it is necessary to secure a gap between the blade plate and the side surface of the louver frame to enable smooth rotation of the blade plate. There is concern that light leakage will occur.

  On the other hand, as another problem, for example, simply installing a part for preventing light leakage from the louver frame, such as a blindfold that protrudes from the louver frame toward the slats, the installation or removal of the slats There is a concern that the ease of the process may be impaired. That is, it is necessary to have a structure that ensures the ease of installation of the blades and the ease of removal.

  In view of the above problems, the present invention proposes a louver having a novel structure that can solve the problem of light leakage caused by the existence of a gap between the blade plate and the louver frame.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

That is, as described in claim 1,
A louver provided with a long cover material provided on a louver frame that rotatably supports a blade,
An expected surface portion for covering the expected surface of the louver frame;
A shielding portion disposed at one end portion of the expected direction of the expected surface portion;
